The Separate Energy Storage Device (SESD) based Dynamic Voltage Restorer (DVR) used to protect consumers from the grid voltage fluctuations like Long and Short-Duration Voltage Variations. This paper analyses the operation principle of the SESD based DVR and its design is based on simple PI control method and decision making switch to compensate Long and Short-Duration Voltage Variations. During short-duration voltage variation super capacitor and fuel cell hybrid system is used to compensate the fault. In the same way during long-duration voltage variation photovoltaic (PV) system or backup battery or other grid is used to compensate the fault based on the availability. Using MATLAB/SIMULINK, the models of the SESD based DVR is establish, and the simulation tests are performed to evaluate the system performances.

During short-duration voltage variation super capacitor and fuel cell hybrid system is used to compensate the fault. In the same way during long-duration voltage variation photovoltaic (PV) system or backup battery or other grid is used to compensate the fault based on the availability.
